Kutch was previously believed to be impoverished in the Late Jurassic ammonite diversity. Recent intensive sampling yielded several new records of genera of different taxonomic affinities. Results of this research are presented here, based on the description of Corongoceras cf. lotenoense , C. sp. A; Himalayites sp.A (Himalayites seideli, Himalayites stoliczkai, Himalayites hyphasis (Blandford), Himalayites ventricosus are also figured); Durangites cf. heilprini, D. sp. A and D. sp. B; Tithopeltoceras lakhaparense, Blanfordiceras sp. A and Pterolytoceras sutile. Additionally, we also present a systematic revision of Micracanthoceras Spath,1925, Aulacosphinctes Uhlig, 1910 and Umiaites Spath, 1931. All previously described Kutch species of Micracanthoceras have been found to belong to the type species, M. micrcanthus. Umiaites. Previously known as endemic only to Kutch, it appears to be the macroconch of the better known Proniceras Burckhardt, 1919. Kutch thus, appears to be taxonomically more diverse than previously assumed during the Late Tithonian.
